1 Claim.

This invention relates to conductor supports or grids of the type usedin connection with wired equipments where a series of electrical connections are to be taken from a cable at a plurality of points.

The object of this invention is to provide a conductor support of thistype which will be sim' ple, cheap to manufacture and wherein theconductors are held in proper grouped relation in a positive andefiective manner without sewing. The elimination of sewing allows easytracing of the leads in the grid.

According to the invention a plurality of wire members are bent to formopen loops which may be of any desired geometrical figure and secured asby welding them in spaced relation and perpendicularly to thelongitudinal axis of a supporting bar, the supporting bar having across-section registering with similar portions of the wire loops attheir welded points and the ends of the Wires are bent inwardly toprovide guiding passageways for facilitating the entrance of theconductors in the loops of the support thus formed.

This support avoids the usual sewing of the conductors before or aftertheir connections to the terminals of the different electrical apparatusand is more economical.

Other novel features and advantages of the invention will appear fromthe following descrip- 0 tion and by the claim appended thereto,reference being had to the accompanying drawing in which,

Fig. 1 is a perspective view of the support bar showing the manner ofdistributing the conductors for connection to the electrical apparatussecured to a mounting plate;

Fig. 2 is a perspective enlarged view of a portion of the conductorsupport shown in Fig. 1;

Fig. 3 is a perspective view of a modification 40 of the conductorsupport shown in Fig. 1;

Fig. 4 is a modified form of support in which a piece of wire is bent toform a series of triangular loops welded at the edge of a flatsupporting bar; and

Fig. 5 is a perspective view of a modification of the supporting barshown in Fig. 4.

As shown in Fig. l of the drawing the sets of conductors W, W1, W2, W3,W4, W5, and We, for example, which connect with the electrical apparatusX, X1, X2, X3, X4, X5, and X6 extend in axial relation with respect tothe supporting bar it] thus forming a shelf on which these conductorsrest and are deviated from such direction around the substantiallyrectangularly shaped loops of wires as L, L1, L2, L3, L4, L5, and Lewhich aiiord rounded surfaces for preventing the tearing or cutting ofthe insulating covering of the conductors W, W1, W2, etc.

Portions of the wire loops L, L1, L2, etc. register with the geometricalcross-section of the bar I0,

the vertically disposed edge of which is rolled outwardly to provide arounded surface on which the sets of conductors W, W1, W2, etc. rest. Inthe rounded edge portion of this bar is formed a plurality of notches llbest seen in Fig. 2 provided for readily locating the wire loops L, L1,L2, etc. in predetermined space relation with respect to the electricalapparatus X, X1, X2, etc. on the supporting bar l2, these wire loopsbeing secured to the bar If! as by welding and the ends l3 and Id ofthese loops are bent inwardly to provide guiding passageways forfacilitating the entrance of the conductors in the loops.

In the modification shown in Fig. 3 the bar ID has an arcuatedcross-section and one of its longitudinal edges is outwardly rolled toprovide a rounded surface to prevent the damaging of the insulatingcovering of the conductors, and this edge like the bar shown in Fig. lis provided with a plurality of notches for readily determining thespace relation of the wire loops or rings L, L1, L2, etc. around whichthe conductors W, W1, etc. are bent in a direction leading toward theterminals of the electrical apparatus X, X1, X2, etc. for connectiontherewith as shown in Fig. 1 and the ends ISA and MA of the wire loopsare rounded and bent inwardly as shown in Figs. 1, 2, and 3 in order tofacilitate the entrance of the conductors in the loops.

In the modified form shown in Fig. 4 a piece of wire is bent as to forma series of triangularly shaped openings P, P1, and P2 having outwardlyflaring passageways, such as E, E1, and E2 provided to facilitate theentrance of the conductors in the triangular openings P, P1, and P2 andthe coaxial portions C, C1, and C2 of the wire Y are secured as bywelding to one edge of the bar H) which in this modified form is ofrectangular cross-section.

In the modification shown in Fig. 5 the bar It) is preferably of rightangle cross-section and openings, such as A and A1 similar to theopenings P, P1, and P2 shown in Fig. 4 are punched from the bar it andholes such as 20 are provided at each end of the bar for securing it toa bracket not shown extending from the support I2 to which theelectrical apparatus are securely mounted.

It is understood that minor changes may be made as to form and size ofthe parts Without departing from the spirit and scope of the appendedclaim.

What is claimed is:

A supporting device for wire conductors comprising a bar made of a flatstrip serving as a shelf for the conductors, a plurality of loop membersopen at one side and secured to one edge of said bar, said loop membershaving similar portions forming guideways for facilitating the entranceof the wire in said loop members.
